# DNS Whakamuri

Source: https://support.kapsulehost.com/mi-nz/cloud-servers-reverse-dns

Ka huri te DNS whakamuri i te wāhitau IP o tō tūmau ki tētahi ingoa, pērā i `mail.example.com`. Ka tirohia e ngā tūmau īmēra i mua i tō rātou whakaae ki ngā īmēra mai i a koe, nō reira whakaritea i mua i te tuku a tō tūmau i tētahi īmēra. Ka whakaritea e koe mō ia wāhitau i te ripa **Whatunga** o te tūmau i KPanel.

## I Mua i Tō Tīmata

Ka whai hua noa te DNS whakamuri ina hāngai te ingoa me te wāhitau i ngā ahunga e rua:

1. Kōwhirihia te ingoa kaiwhakarato, hei tauira `mail.example.com`.
2. I te DNS o tō rohe, tāpirihia he pūkete A (me tētahi pūkete AAAA mō IPv6) e tohu ana i taua ingoa ki te wāhitau IP o tō tūmau.
3. Tatari kia mahi te pūkete. Me tā `dig +short mail.example.com` i te IP o tō tūmau.

Kātahi ka whakarite i te DNS whakamuri ki te ingoa ōrite. Ko tētahi ingoa DNS whakamuri kāore he pūkete DNS hāngai, he kino ake mō te īmēra i te kore rawa. Tirohia [Te Tāpiri me te Hono i Tō Rohe](https://support.kapsulehost.com/mi-nz/adding-your-domain) mēnā kei a mātou te DNS o tō rohe.

## Te Whakarite i te DNS Whakamuri

1. Takiuru ki [KPanel](https://kpanel.kapsulehost.com).
2. I te pae taha, huakina te wāhanga mō tō momo tūmau, hei tauira **Standard Cores**, kātahi ka pāwhiri i tō tūmau.
3. I te tahua o te tūmau, pāwhiritia **Whatunga**.
4. I raro i **IP Addresses**, pāwhiritia **Whakatika** i te taha o te wāhitau.
5. Patohia te ingoa kaiwhakarato katoa, hei tauira `mail.example.com`.
6. Pāwhiritia **Save Reverse DNS**. Ka kī a KPanel "Kua oti."

Ka whakaatu ia wāhitau i te "DNS whakamuri:" me tōna ingoa o nāianei, i te **Kāore i tautuhia** rānei. Whakaritea motuhaketia a IPv4 me IPv6 mēnā ka tuku tō tūmau i te īmēra mā ngā mea e rua.

Ka whakaaturia te ripa **Whatunga** ina tautoko tō tūmau i te DNS whakamuri. Ka puta a **Whakatika** mō ia wāhitau ka taea te huri i tōna DNS whakamuri.

## Ngā Wāhitau IPv4 Tāpiri

He DNS whakamuri ake tō tētahi wāhitau IPv4 tāpiri. Whakaritea i te ripa **Whatunga** o te tūmau pērā i ētahi atu wāhitau, huakina rānei **Ngā tāpiringa**, kātahi ko **Extra IPv4**, kōwhirihia te wāhitau, ā, pāwhiritia **Change Reverse DNS**.

## Te Tirotiro Kei te Mahi

Mai i tētahi rorohiko, whakahaerehia:

```sh
dig +short -x 203.0.113.10
```

Whakamahia tō ake wāhitau IP. Me tā i tō ingoa kaiwhakarato me tētahi ira i muri. Ka roa pea te puta o tētahi huringa ki ngā wāhi katoa.

## Ngā Tūmau Metal i Tonoa i Mua i te Rārangi Hou

I ngā tūmau Metal tawhito, huakina te whārangi **Whakahaere tūmau pūkaha** o te tūmau, ā, whakamahia te kāri **DNS whakamuri**. Pāwhiritia **Whakatika** i tētahi wāhitau, patohia te ingoa kaiwhakarato, ā, pāwhiritia **Tiaki**. Tirohia [Te Whakahaere i Tētahi Tūmau Dedicated](https://support.kapsulehost.com/mi-nz/dedicated-servers-management).

## Te Whakatika Raru

**"Tāurutia he ingoa kaiwhakarato katoa, pērā i mail.example.com."** Patohia te ingoa katoa, tae atu ki te rohe. Kāore e rawaka tētahi kupu kotahi pērā i `mail`.

**"Ehara taua wāhitau i tēnei tūmau."** Kōwhirihia tētahi wāhitau kua whakarārangitia i te ripa **Whatunga** o tēnei tūmau.

**Kei te whakakāhoretia tonutia te īmēra.** Tirohia kei te tohu te pūkete A o te ingoa ki te IP ōrite, ā, kei tō rohe ngā pūkete SPF, DKIM me DMARC mō te tūmau e tuku ana.

**"Ka taea e tō tūranga te mātakitaki i tēnei tūmau engari kāore e taea te panoni."** Ko ngā tūranga Kaipupuri me Kaiwhakahaere anake ka taea te huri i te DNS whakamuri. Pātai ki te kaipupuri pūkete.
